【摘要】 在数据库受到攻击的情况下,能够继续提供服务并根据攻击造成的不同损害进行自适应调整是非常重要的问题,所以本文首次提出基于角色访问的自适应容侵数据库结构。该结构根据用户的角色、入侵的历史纪录、系统状态等因素动态采取不同的容侵策略,因此在保证系统持续提供服务的同时,提高数据库的容侵能力。更多还原

【Abstract】 For intrusion-tolerant database systems, it’s crucial for them to dynamically change their behavior and continue delivering essential services under malicious attacks. Thus, combined with role-based access control, we propose an adaptive architecture to intrusion-tolerant databases for the first time in the literature. For systems intruded by malicious users, different adaptive intrusion-tolerant policies are taken in terms of users’ different roles, historical logs of intrusion, different system states etc. Therefore, while keeping delivering essential services, we can enhance the system’s intrusion-tolerant ability.更多还原
